Beschreibung

The ADP1034 is high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting buck boost dc-to-dc regulator, and a buck dc-todc regulator, providing three isolated power rails. The ADP1034 includes four high speed serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel to channel applications where low power dissipation and small solution size are required.

Eigenschaften

  • Wide input supply voltage range: 4.5 V to 60 V
  • Integrated flyback power switch
  • Generates isolated, independent, resistor-programmable bipolar outputs and factory-programmable buck output
  • VOUT1: 6 V to 28 V
  • VOUT2: 5.0 V
  • VOUT3: −24 V to −2 V
  • 86% typical efficiency at 2.61 W output power
  • Programmable power control pin (PPC_IN) for adjusting VOUT1through serial command
  • Uses a 1:1 ratio transformer for simplified transformer design
  • Adjustable switching frequency via SYNC input
  • Peak current limiting and overvoltage protection
  • Internal compensation and soft start control per regulator
  • Precision enable input
  • High speed, low propagation delay, SPI signal isolation channels
  • Three 100 kbps general-purpose isolated data channels
  • 41-lead, 9 mm × 7 mm LFCSP form factor enables small overall solution size
  • −40°C to +125°C operating junction temperature range
  • Safety and regulatory approvals (pending)
  • CISPR11 Class B radiated emission
  • UL recognition: 2500 V rms for 1 minute per UL 1577
  • CSA Component Acceptance Notice 5A
  • 300 V rms basic insulation between slave, master, and fieldpower domains (IEC 61010-1, pending)
  • VDE certificate of conformity
  • DIN V VDE 0884-10 (VDE 0884-10):2006-12
  • VIORM = 565 V peak

Typische Anwendungen
